' In. the preparation of fursand skins for manufacture into` garments, it is usual to treat the skins by stretchingv themand tacking them on ai board or block while in said stretched condition untilsuch time asv they have lost theirv tendency to contract when freed.

It isf a rather diicult operation to rst stretch the skin and hold it in stretched' condition while the tacking'is taking place, and the object ofthe present invention is to devise apparatus whichwill grip the skin to enable it to be stretched, and which, without losing the grip on the skin, will 4 Claims.

l mally. tends to move; the hammer downwardly to automatically drive staples or tacks to hold the l In the` drawings like numerals of reference iny dicate corresponding parts in the different iigures.

The apparatus includes a pair of pliers comprising a pair of members l and 2 pivoted together at 3 to rock on a horizontal axis. The

member l comprises the lower jaw 4 and operating handle 4, while the member 2 comprises the upper jaw 6 and operating handle 1. A spring 8 is provided between the handles and 1 tending to hold the latter apart and thus force the jaws 4 and 5 together. The adjacent faces of the jaws will be suitably serrated or roughened to more rmly grip the skin 9, which is indicated in dotted lines.

Extending transversely of the upper jaw 6 is the staple magazine I8, in which the staples are mounted on a guide ll along which they are moved to the driving position by a sliding member l2 operated by a spring I3.

Extending upwardly from the end of the magazine is a guide I4 in which is vertically slidable the hammer I5,'which is provided with a head IB by means vof which it may be manually operated when desired.

It is preferred, however, that the control of the hammer be automatic, and to eiect the driving of the hammer a leaf spring Il is provided having one end secured to the upper side of the staple magazine and its free end projecting into anotch l 8 in the hammer. This leaf spring nordrivetheV staple.

Extending upwardly from the upper fjaw 6 slightly inY advance of the pivot 3 are posts i9 in which is journalled a shaft 25 from which extendsapost. 2| on which is horizontally swingable abent leverI 22'. One end of this lever22 is provided with spaced pins. 23 which extend one above-` and. one below the handle 5, so as to cause said: lever to, swing on. the shaft. 2ilv withsaid handle 5. The other end of this lever isv adapted to engage under a shoulder 24 on theside of the'hammer i5. A. spring, 25, having one end connected with the lever and its other end connested with an arm, 26 extending from one of the posts I9, tends to hold the leverengaging under the. shoulder 2li in hammerelifting position.

The; operation of the device isV as follows. The jaws. lila-nd. t are forced: together to grip the skin between them andby pulling on .the device'the skin.v is. stretched to the desired extent. In

forcing the jaws 4 and 6. together, the handle 5 rocks; the lever 2 2 in the vertical plane to lift thehammer l5. and the hammer is thus; held lraised while the-skin is being stretched. When the skin is sufiiciently stretched, the lever 22 is rocked sidewise on the pivot 2| (see Fig. 3) to disengage the end of the lever from the shoulder 24, to allow the spring Il to force the hammer downwardly heavily against the staple below to drive the latter. When the staple is driven, the handles 5 and 'l are allowed to separate and a new grip is taken at another position of the skin to stretch it. Upon separation of the handles 5 and l, jaws 4 and 6 also separate and since lever 22 is carried by handle l at its jaw end 6, outward movement of handle 5 resting between pins 23-23 of lever 22 rocks the opposite end of the lever 22 to place its end in line with the notch I8 on the hammer, where the end is then moved below the shoulder 24 in the hammer.

It will be seen that the work of stretching the skin and driving the staples may be done by One person, whether the hammer is manually or automatically operated. In the case of the automatic operation of the hammer, the stretching of the skin and driving of the staples may be done with one hand.

It will be understood that various alterations may be made in the shape and arrangement of the various parts without departing from the spirit of the invention.

What is claimed is:

1. In a fur blocker and fastener, the combination with a pair of lever members pivotally connected intermediate their ends to form opposed gripping jaws at one side of the pivot and opposed handles at the other side of the pivot, of a fastener magazine mounted on one of the jaws and having a fastener outlet beyond the gripping surface of the jaw; a hammer movable to and from the outlet; spring means normally tending to move the hammer towards the outlet;- means operable by a handle for engagement with the hammer to move the hammer away from the outlet against the action of the spring; and means for disengaging said engageable means to permit the spring to move the hammer towards the outlet.

2. In a fur blocker and fastener, the combination with a pair of levei` members pivotally con-v nected intermediate their ends to form opposed gripping jaws at one side of the pivot and opposed handles at the other side of the pivot, of

`a fastener magazine mounted on one of the jaws mediate its ends on said magazine-carrying jaw; means at one end of said hammer-controlling lever engageable by the handle of the opposing jaw, the other end of said hammer-controlling lever being adapted to engage with a notch on the hammer to move the hammer away from the fastener outlet; and means to release the means at said one end from the hammer to allow the spring to move the hammer towards the fastener outlet.

3. In a fur blocker and fastener, the combination with a pair of lever members pivotally connected intermediate their ends to form opposed gripping jaws at one side of the pivot and pposed handles at the other side of the pivot, of a fastener magazine mounted on one of the jaws and having a fastener outlet beyond the gripping surface of the jaw; a hammer movable to and .from the outlet; spring means normally tend-` ing to move the hammer towards the outlet; a

hammer-controlling lever pivotally supported intermediate its ends on said magazine-carrying jaw, means to swing said hammer-controlling lever in the same plane as the lever members and also in a plane transversely thereof; means at one end of said hammer-controlling lever engageable by the handle of the opposing jaw, the other end of said hammer-controlling lever being adapted to engage with the hammer to move the hammer away from the fastener outlet; and means to release the hammer to permit the spring to move the fastener outlet to drive a fastener.

4. In a fur blocker and fastener, the combination with a pair of lever members pivotally connected intermediate their ends to form opposed gripping jaws at one side of the pivot and opposed handles at the other side of the pivot, of fastener feeding and driving means mounted on a gripping jaw and having a fastener outlet beyond the gripping surface of the said fastener feeding and driving means including resilient means tending to move the driving portion of said means towards the fastener outlet; and means adapted to engage with the driving portion to move said driving portion away from the fastener outlet; and means to release the driving portion to allow the resilient means to move the driving portion towards the fastener outlet.
